Features:
• Double beam monochromator and dual lens flow cell produce superelevation sensitivity.
Using the D2 lamp and solar battery, double beam monochromator made up of 1200 /mm concave raster, and dual lens flow tank which is processed with precision ,;wavelength is adjusted by microprocessor with high accuracy.,24A/D of two-circuit high speed sampling. These components ensures the low noise of the detector, low drift ang high sensitivity ..
• Original pressure feedback control system reduces the dead volume of the system to the largest extent.
The adoption of advanced pressure feedback control system and abandonment of pipeline mixer with bigger dead volume not only reduce dead volume of the flow path greatly but also improve the stability of the pump flow due to the appliance of pressure feedback speed-change technology.
• Unique online clean function ensures the durability and easy maintenance of the instrument.
Function of unique online plunger rod clean can achieve automatic cleaning by setting the time procedure,which prevent plunger rod from fray resulting from the formation of buffer salt greatly and prevent the accumulation of little adsorbate on the pump head caused in the process of flow .
• Building block type combination and many kinds of models for separation and detection
Various separation examination pattern, isocratic separation pattern, gradient separation pattern, time flux procedure separation pattern, examination pattern of single wave length, examination pattern of stops flow wave length scanning and the examination pattern of time wave length procedure.
• Super strong control function, intellectualized supervisory system, function of self-checking and self-adjustment ,etc
Super strong instrument control function ,which include the overall control from mobile phase management to output of chromatograph analysis data,ensures the accuracy and reliability of analysis data.As long as the instrument is equipped with automatic sample and corresponding procedures are set,unattended LC analysis is achievable.
